Abstract

L'invention concerne un siège pour véhicule à moteur comprenant une première partie de montage et une seconde partie de montage. La première partie de montage peut pivoter par rapport à la seconde partie de montage autour d'un axe de rotation. Le siège de véhicule comprend également une unité de transmission qui permet le réglage de la première partie de montage de manière angulaire par rapport à la seconde partie de montage. Le dossier du siège de véhicule s'étend verticalement et de manière sensiblement perpendiculaire à la partie assise dans une première position, tout en pivotant par rapport à la première position autour de l'axe de rotation dans une seconde position. Le siège de véhicule comprend également un dispositif de verrouillage (6) qui comprend au moins une surface de blocage (15, 15') et qui provoque le verrouillage de la première partie de montage et de la seconde partie de montage dans la seconde position, de manière à ce qu'une résistance surmontable manuellement est créée, ce qui rend la rotation du dossier plus difficile dans la première position. Dans la seconde position, les surfaces de blocage des dispositifsde verrouillage sont disposés l'une sur l'autre, dans le sens radial par rapport à l'axe de rotation.
